FIGS. 1 and 1 a illustrate a prehung door and frame assembly 30 with two corner protector containers 10 positioned in the tipper right and left corners of the prehung door assembly 30 and container embodiment 100 positioned on the lower right (FIG. 1) side i.e. the hinge jamb 32. FIG. 1 shows the cavity side 39 and FIG. 1a the door side of the prehung door and frame assembly 30. In a prehung door assembly the door 34 is usually hung from the hinge jamb 32 with hinges 36 so the door 34 is flush to the edges of head jamb 31, hinge jamb 32 and striker jamb 33 on one side of the assembly (FIG. 1a ). Because of the width of the jambs a cavity 39 is formed on the other side of the assembly. The door 34 usually has predrilled holes 35 for mounting lock and handle. The three jambs have a stop 37 running parallel to their edges on the cavity side 39 to prevent the door from moving through the frame formed by the jambs when closed. Two of the corner protector containers 10 are shown mounted in the cavity 39, one in the right upper corner and one in the left upper corner. Container embodiment 100 is shown mounted in the cavity 39 on the hinge jamb 32. The corner protector container 10 is held in place when the corner protector container 10 is assembled over the jambs. It can be further secured with a shipping band 38. In this embodiment the corner protector container 10 is rectangular, it could also be square. The length and width of the corner proctor container can range from about a few inches to about ninety percent of the length and width of the cavity 39, The width of side walls 12 and 14 (W1 and W3) i.e. depth, is preferably no greater than the depth of the cavity 39 or the stops 37 whichever is less so the container front wall 15 is flush with the top edges of the jambs or the front wall is below the level of the edges of the jambs. The corner protector container 10 slips over the head jamb by inserting it into the jamb channel 23 and either the hinge jamb 32 or the striker jamb 33 by inserting it into the second jamb channel 24 and the container 22 sits inside the cavity 39 and the container front wall 15 is shown flush with the edges of the jambs. The open end formed by the top edges of 12, 13 and 14 end of the container portion 22 abuts against inside of the jamb to hold articles put into the container 22 for shipment with the prehung door and frame assembly 30. The jamb panel 17 of the corner protector container 10 fits over either the head jamb 31 or the hinge jamb 32 and the second jamb panel 18 fits over the other jamb. The door side panel 20 folds down over and fits flash with the door 34 and ties into the jamb panel 17 and locks the corner protector 10 onto the prehung door and frame assembly (see FIG. 1a ).

Referring to FIGS. 2, 8 and 13, the corner protector container 10 can be formed from a unitary, planar, generally rectangular paperboard blank 11 and the container embodiment 100 from, blank 110 or 210. in the FIGS. a dashed—line indicates fold lines and an x-x-x line represents a cut line (i.e. the paper board is cut along this line to permit folding of that portion of the blank 11). Fold lines are preferably scored such as by press scoring to reduce the paper stiffness along the fold line enabling an accurate fold of the paper board alone the designated fold lines.

Referring to FIG. 2, blank 11 includes a container first side wall 12 connected by a fold line 12 a to container back wall 13 which will face toward the door 34 when folded and placed. The container back wall 13 has locking key 13 a extending from near the center of its lower edge along fold line 13 b. The container back wall 13 is connected by a fold line 14 a to container second side wall 14. The container second side wall 14 is connected by a fold line 15 b to a container front wall 15 which faces toward the outside of the cavity. Extending from the top of the container front wall 15 and connected by a fold line 15 c is a tie 15 a which has a cut line 15 d running from, the top to the fold line 15 c. The tie 15 a preferably has a tapering or rounded top edge to facilitate ease in folding the blank into the corner protector container 10. In the embodiment in FIG. 2 extending from the bottom edge of the container front wall 15 and connected thereto by fold line 16 b is a container bottom 16 which functions to close the bottom of the container 22. Extending from the bottom edge of the container bottom 16 through fold line 16 c is a bottom flap 21. A key slot 16 a is centrally formed along the fold line 16 c for receiving the locking key 13 a when forming the corner protector container 10. The container bottom 16 has a width W4 starting at fold line 15 b no greater than the width W2 of the container back wall 13 and less than the width W5 of the container front wall 15. The difference between W2 and W5 forms a jamb channel 23 when the corner protector container 50 is folded into shape. The container bottom 16 can be less than the width of the back wall 16 but should be wide enough to retain the articles placed in the container for shipment. The container bottom 16 has a length L3 equal to the width W1 of the container first side wall 12 which preferably has the same width or can. be less than W3 as the container second side wall 14. The bottom flap 21 has the same width W4 as the container bottom 16 and a length no longer than the length of the container bottom 16. Alternatively the container bottom 16 can be formed by extending the container bottom 16 from the first side 12 wall as shown in FIG. 13 with the locking key being formed at the bottom of the second side wall. The reverse can also be employed i.e. extending the bottom 16 from the bottom of the second side wall 14 with the locking key being formed at the bottom of the first side wall 12. Connected to container front wall 15 by fold line 17 b is a jamb panel 17. Defining the top edge of jamb panel 17 is fold line 17 c. Formed along the lower edge of the fold line 17 c is a centrally located key slot 17 a for receiving key 19 a. Connected to the upper part of jamb panel 17 through fold line 17 c is a second jamb panel 18. The width W6 of the jamb panels 17 and 18 is about the same as width of the jambs making up the frame of the prehung door and frame assembly 30 to which the corner protector container 10 is attached. The fold lines 15 c, 17 c and 20 c lie in a straight line. The length L2 of the jamb panel 17 and door side panel 20 and the fold line 17 b is the same as the longest length of the container front wall 15. The length L2 is longer than the length L1 by an amount at least as great as the thickness of the jambs of the frame of the prehung door and frame assembly 30. When folded the additional length L2 forms a second jamb channel 24 in the corner protector container 10 between the top of the first side wall 12, back wall 13 and second side wall 14 when the container is folded into shape. In FIG. 2 the bottom edges of 12, 13, 14, fold line 16 b, 17, and 20 are aligned in a straight line, however the bottom edges of 17 and 20 can be above or below the bottom edges of edges of 12, 13, 14 and fold line 16 b, Connected to the top edge of the second jamb panel 18 is fold under flap 19 that has a width W8 slightly narrower than the width W6 of the second jamb panel 18. The fold under flap 19 is connected to the second jamb panel 18 through two parallel fold lines 18 a and 19 b. Defined in the top edge of the fold under flap 19 is key 19 a that mates with key slot 17 a when the corner protector container 10 is folded into shape. The length L4 of the jamb panel 18 can vary. The length L5 of the fold under flap 19 is about the same as the length L4 of the jamb panel 18. In this embodiment the width W8 of the fold down under flap 19 is slightly less than the width of the jamb panel 18. This facilitates the insertion of the tie 15 a and door side tie 20 a into the envelope 25 formed when the fold under flap is folded into place under the jamb panel 18. Connected to jamb panel 17 through fold line 20 b is door side panel 20. The width W7 of the door side panel 20 can vary. Along the top edge of the door side pane 120 is fold line 20 c that has connected to it door side tie 20 a. Door side tie 20 a has cut line 20 d that permits the tie 20 a to be folded down away from the door side panel 20 so that when folded perpendicular to jamb panel 17 the door side tie 20 a, as is tie 15 a, can be inserted into an envelope 25 formed when fold under flap 19 is folded under onto second jamb panel 18 and key 19 a is inserted-into key slot 17 a. This locks the door side panel into second jamb panel 18. Friction between the parts secures the corner protector container 10 on to the corner of where the head jamb 31 connects to either the hinge jamb 32 or the strike jamb 33 of the frame of the prehung door and frame 30. All parts 12, 13, 14, 15, 16, 17, 18, 19 and 20 are rectangular having square comers as defined by their edges and fold lines. Ties 15 a and 2 a axe preferably rectangular with tapered or rounded upper edges to facilitate insertion into the envelope 25 formed when fold under flap 19 is folded under second jamb panel 18. The length of the outside edge of container first side wall 12, fold line 12 a, 13, fold line 14 a and fold line 15 b are all about the same L1. Fold line 17 b, 20 b and the outside edge of door side panel 20 all have the same length L2, said L2 is longer than L1 so that when the container corner protector 10 is folded a jamb channel 23 is formed along the top edges of wall 13, 14 and fold line 15 c. The embodiment in FIG. 2 shows key slots and keys to secure the bottom and fold under flap. Other means of securing such as tape, adhesives, staples and the like can be used.

The container 22 is formed by folding container first side wall 12 along fold line 12 a perpendicular to container back wall 13. Container back wall 13 is folded along fold line 14 a perpendicular to container second side wall 14 so the front edge of container first side wall 12 touches the inside of the container front wall 15. When so folded the face of first side wall 12 faces the inside wall of jamb panel 17 forming a second jamb channel 24. Width W1 and W3 are preferably no greater than the depth of the cavity 39 (edge of jambs to the face of the door 34 or stops 37 whichever is less).

To assemble the corner protector container 10 and attach it to the cavity 39 side of the prehung door and frame assembly 30 frame the fold under flap 19 is folded 180 degrees along 19 b and 18 a, onto second jamb panel 18 and secured by key 19 a sliding into key slot 17 a. This fold forms an envelope 25 into which ties 15 a and 20 a are later inserted to lock the corner protector container 10 onto the head jamb 31 and either the hinge jamb 32 or the striker jamb 33 of the prehung door and frame assembly 30.

The formed second jamb 18 & 19 is then folded along fold line 17 c until perpendicular to jamb panel 17. Door side tie 20 a is then folded along fold line 20 c and tie 15 a is folded along fold line 15 c until perpendicular to jamb panel 17.

Door side panel 20 is then folded along fold line 20 b until perpendicular to jamb panel 17. Door side tie 20 a is slid into the newly formed envelope 25 formed between second jamb panel 18 and fold under flap 19.

Container 22 is formed by folding container bottom 16 along fold line 16 b until perpendicular to container front wall 15. Bottom flap 21 is folded along fold line 16 c until perpendicular to contain bottom 16 and container first side wall 12 is folded along fold line 12 a until perpendicular to container back wall 13.

Locking key 13 a is then folded perpendicular to container back wall 13. Next the container back wall 13 is folded along fold line 14 a until perpendicular to container second side wall 14 and container second side wall 14 is folded along fold line 15 b until perpendicular to container front wall 15. Locking key 13 a is then inserted into key slot 16 a. There is formed container 22 having an opening at the top of folded 12, 13 and 14. The opening is where hardware or the like can be placed into the container 22. The opening abuts against the inside of the jamb when the corner protector container 10 is secured at the corner of the frame.

The final assembly is formed by placing desired contents into newly formed container 22 and then placing corner protector container 10 over the corner formed by the jambs of the prehung door and frame assembly 30 using the channels 23 and 24 formed by the folding process. The container front wall 15 is then folded along fold line 17 b until perpendicular to jamb panel 17, sliding tie 15 a into the envelope 25 formed by 18 and 19 which locks the corner protector container 10 around the corner formed by the jambs of the prehung door and frame assembly 30.

FIG. 7 illustrates an intermediate stage of folding of corner protector container 10.

Referring to FIGS. 8-13, the container embodiment 100 is formed from a unitary, planar rectangular paperboard blank 110, (FIG. 8) or another embodiment of a blank 210 shown in FIG. 13.

Blank 110 includes a container first side wall 111 connected by a fold line 111 a to container back wall 112. In the embodiment shown in FIG. S the container back wall 112 has first locking key 112 a extending from near the center of its lower edge along fold line 112 c. The container back wall 112 has a second locking key 112 b extending from near the center of upper edge along fold line 112 d. The container back wall 112 is connected by a fold line 113 a to container second side wall 113. The container second side wall 113 is connected by a fold line 114 a to a container front wall 114. Extending from the bottom of the container front wall 114 and connected by a fold line 114 c is container bottom 115. Extending from the bottom edge of container bottom 115 through fold line 115 b is bottom flap 119. A key slop 115 a is centrally located along fold line 115 b for receiving the locking key 12 a when forming the container embodiment 100. Extending from the top edge of the container front wall 114 and connected thereto by fold line 114 b is a container top 116. Extending from the top edge of the container top 116 through fold line 116 b is a top flap 120. A slot 116 a is centrally formed along the fold line 116 b for receiving the locking key 112 b when forming the container embodiment 100. The container bottom 115 has a width W4 shown here as starting along fold line 114 a about equal to the width W2 of the container back wall 112 and less than the width W5 of container front wall 114. The container bottom 115 has a length L3 and the container top 116 has a length L4 equal to the width W1 of the container first side wall 111 which has about the same width W3 as the container second side wall 113. The bottom flap 119 and the top flap 116 have about the same width W4 as the container bottom 115 and the container top 116 (which is also about equal to W4) and a length no longer than the length L3 and L4 of the container bottom 115 and container top 116. Connected to container front wall 114 by fold line 117 a is a jamb panel 117. Connected to the jamb panel 117 through fold line 117 b is door side panel 118. The width W6 of jamb panel 117 is about the same as width of the jambs making up the frame of the prehung door and frame assembly 30. The length L2 of the jamb panel 117 and door side panel 118 and the fold line 117 b is preferably the same as, or as shown in FIG. 8, is greater than L1. The width W5 is greater than width W2. When folded the additional length forms a jamb channel 123 between, the first side wall 111 and jamb panel 117 in the container embodiment 100. The bottom edge of 111, 112, 113, and fold lines 111 a, 113 a, 114 a, 114 b 114 c and 117 a are aligned in a straight line. The width W7 of the door side panel 118 can vary. All parts 111, 112, 113, 114, 115, 116, 117, and 118 are rectangular having square corners as defined by their edges and fold lines. Width W7 of the door side panel 118 is preferably at least about the same as the thickness of the jamb members of the frame. The length of the outside edge of container first side wall 111, fold line 111 a, fold line 113 a, fold line 114 a and 117 a are all the same, i.e. L1. Fold line 117 b and the outside edge of door side panel 118 all about the same length L2 and said L2 is preferably longer than L1. Key locks 112 a and 112 b and key slots 115 a and 116 a are illustrated as the means for securing the container top 116 and container bottom, however, other means of securing can be employed such as for example, tape, adhesives, staples or the like.

The container 121 is formed by folding container first side wall 111 along fold line 111 a perpendicular to container back wall 112. Container back wall 112 is folded along fold line 113 a perpendicular to container second side wall 113 so the front edge of container first side wall 111 touches the inside of the container front wall 114. When so folded the lace of first side wall 111 faces the inside wall of jamb panel 117 when folded along fold line 117 a perpendicular to container front wall 114 forming a jamb channel 123. Container bottom 115 is folded perpendicular to container front wall 114 along fold line 114 c and bottom flab 119 is folded perpendicular to container bottom 115 along fold line 115 b and key slot 115 a is engaged with previously folded container back wall 112 and first locking key 112 a. Container top 116 is folded perpendicular along fold line 114 b to front wall 114 to face container bottom 115. Top flap 120 is folded perpendicular to container top 116 and key slot 116 b is engaged with second locking key 112 b.

To assemble the container 121 and attach to the frame and into the cavity 39 side of the prehung door assembly 30 frame, the contents of the container are placed inside the container either before the container top 116 or the container bottom 115 are secured (or the container can be filled through the first side wall 111 before it is closed). The container is then placed into the cavity 39 with the container first wall 111 snug against the inside surface of one of the jambs. The jamb panel 117 is then folded perpendicular along fold line 117 a, to form the jamb channel 123, so that the inside surface of jamb panel fits flush with the outside surface of the frame jamb. Door side panel 118 is then folded along fold line 117 b perpendicular to jamb panel 117 to fit flush with the door side edge of the jamb and secured in place with glue, staple, or banding. In one embodiment the container embodiment 100 is employed with a standard jamb corner protector 122 as shown in FIGS. 11 and 12 such that the standard jamb corner protector holds the container embodiment 100 in place.

FIGS. 9 and 10 illustrate the container embodiment 100 in various stages of folding before

being attached to a jamb so the container 121 sits in the inside of cavity 39. When attached the size of the container depth wise (W1 and W3) is preferably no greater than the depth of the cavity 39 so the container front wall 114 is essentially the same or less than the depth of the cavity.

FIG. 13 illustrates another embodiment of a blank 210 for preparing a container 100. Blank 210 includes a container first side wall 211 connected by a fold line 211 a to container back wall 212. The container back wall 212 is connected by a fold line 213 a to container second side wall 213. The container second side wall 113 is connected by a fold line 114 a to a container front wall 214. Extending from the bottom of the first side wall 211 and connected by a fold line 211 d is container bottom 215. Extending from the bottom edge of container bottom 215 through fold line 215 b is bottom flap 219. A key slop 215 a is centrally located along fold line 215 b for receiving the locking key 213 b extending from the bottom edge of second side wall 213 when forming the container embodiment 100. Extending from the top edge of the second side wall 213 and connected thereto by fold line 213 d is a container top 216. Extending from the top edge of the container top 216 through fold line 216 b is a top flap 220. A key slot 216 a is centrally formed along the fold line 216 b for receiving a locking key 211 b extending form the top edge of first side wall 211 when forming the container embodiment 100. The container bottom 215 and the first side wall 211 have about the same width W1. The container bottom 215 has a length L2 and the container top 216, L3, about equal to the width W2 of the container back wall 212. The container second side wall 213 and the container top have about the same width W3.
